The Centers for Medicare & Medicaid Services (CMS) Center for Consumer Information and Insurance Oversight (CCIIO) is committed to increasing transparency in the Health Insurance Exchanges. While health plan information including benefits, copayments, premiums, and geographic coverage is publicly available on Healthcare.gov, CMS also publishes downloadable public use files (PUFs) so that researchers and other stakeholders can more easily access Exchange data.| www.cms.gov
The Health Insurance Marketplace Calculator, updated with 2025 premium data, provides estimates of health insurance premiums and subsidies for people purchasing insurance on their own in health insurance exchanges (or “Marketplaces”) created by the Affordable Care Act (ACA).| KFF
